-
Speed: Determine the operating speed range of the bearing.
-
Accuracy: Define the required precision and dimensional tolerances for the bearing.
-
Environment: Consider the operating environment, including factors such as temperature, corrosion, and lubrication.
-
Cost and Availability: Balance performance requirements with budgetary constraints and lead times.
Common Mistakes to Avoid
To ensure optimal bearing performance and longevity, it's essential to avoid common mistakes:
-
Improper Mounting: Misalignment or inadequate mounting can lead to premature bearing failure.
-
Incorrect Lubrication: Insufficient or excessive lubrication can compromise bearing life.
-
Overloading: Exceeding the bearing's load capacity can cause damage and reduced lifespan.
-
Contamination: Dirt, debris, or moisture can damage bearings and shorten their service life.
-
Neglecting Maintenance: Regular maintenance and inspections are crucial for detecting and addressing issues before they escalate.
